vas shown, slight cominCr loosened said insulating strips -O will adjust themselves automatically to the rail and fillet, thereby affording the most ef. iicient contact and support for the rupper tread portion of the rail.

eferring to Fig. 4 of the drawings will be seen a slight modification of my invention in which the chair-section M is made of a single are b taking vup wear upon eitherside of the chair. In said modified form the u right portions of the chair each is providedpwiththe concaved seat'Q, which is at an inclination terminates in an angled shoulder Q', for

upon the inner surface of the upright portions and surfaces conveXed, as at R', lar, as at'S, to conform to which they areheld. Th l each insulating-strip R -is similar in outline to the shape of the upper surfaces of the insulating-strips O, before referred to, and are adapted to conform to the curvatuie of the under surface' of the tread and fillet of the rail.

In Fig. 5 of slight modification of my the chair is nated, respectively, by letters T and T,) each of which is bent upon itself at T2, providing means whereby wear Vupon the chair-sections may be t'aken up, and the meeting ends and also angue upper surface of the drawings I have shown a invention in which of the two chair-sections overlapeach other, spaces intervening between.

the ends which overlap to allow for expansionv and shrinkage of the metal incident to variations in the Weather.

and insulation for the rails, and

-useless the insulating Aneath -said insulation being From the foregoing it will be noted that by the provision of a rail-joint made in accordapparatus is afforded, whereby ventilation is afforded to the insulation upon which vthe rail rests, thereby moisture from deteriorating and looseness incident to wear upon any parts of the chair or chair-sections, the removable insulatingfstrips automatically conforming to the contact-surface of the rail,- thereby forming a secure support l so arranged that when desired the removable strips may be easily replaced without removing the chair or chairse`ctions;

What IV claim is f 1. `An insulated railejoint comprising a chairv havin0r a lateral extension adapted to receive the ange of a rail, an insulating material intermediate the bottom of the flange and said-lateral extension'ofthe chair, the rail-supporting surface of the chair underprovided. with the seats upon made up of two sections,.(desig l longitudinal grooves, whereby the insulating material maybe properly ventilated, removf able insulating-strips ysupportedlby the vupf preventing -f rendering material, and any l tion of the chair cent tov one edge longitudinal right portions .of the chair, the latter having a portion thereof bent upon itself formin means whereby wear may be taken up and said insulating-strips heldin contact With the4 under surface of the tread portion of the and the fillet thereof, and insulated means for holding the chair-sections in clamping relation with he rail, as set forth.

2. An insulated rail-joint com chair having' a lateral extension a ate to receive the flange of a rail, an insulatln maferial intermediate zhe bottom ofthe gauge and' said lateral extension of the chair, the rail-supporting surface of the chair underneath said insulation being' provided with risin a material may be properly ventilated a pormovable insulating-stri s mounted one upon each upright ortion of) the chairv and so ar-A ranged that t ey will automatically adjust themselves to the undersurface of the treadl portion of the rail and the fillet, when the wear is taken-up,vand insulated means for holding the chair to the rail, as set forth.

An insulatedrrail-joint com rising a chair havin a lateral extension a apted to receive the lange of a rail, an insulatin material intermediate the bottom of the ange and said lateral extension rail-supporting surface of neath saidinsulation bein provided with grooves, Where y the insulating material may be properly ventilated, a portion of the chair being bent cent to one u right portion ofeach-chair c ined thev chair underupper surfaces conforming to the under surfaces of they tread portions of of the chair, the

loo

the rails and the fillet thereof against Which they are ada ted to beheld by the upright portions of t e chair, yand insulated means for holding the chair to therail, as

4: An insulating rail-Jo chair having inconcaved seats, removable insulatinghaving their under surfaces convexed set forth.

the fiange of the rail,

85 y being bent upon itself afdja-` of the flange of the rail, 4rei whiehthe flange of .portion of the lateral extension of said railadapted to rest upon said seats, 'their upper l surfaces conforming to theunder surface of the tread portion of the rail and theiillet thereof, means for taking up-ihe wear u A)on the chair, and insulated means for holding the chair to the rail, as set forth. l l5. An insulated` rail-joint comprising a chair made up of two sections, one of which is provided with a lateral extension which'- is grooved upon itsupper surface, an insulating material covering said grooves and upon i a rail 1s adapted to rest, a .i

section being provided with an upwardly and l outwardly curved flange, the other-chair-seetion being provided wlth a hook adapted to engage over said curved flange, the rail-supporting chair-section having a portion thereof bent upon itself forming means up wear, the upper ends of the chair-sections having inclined eonoaved seats, removable insulatin -strips resting lpon said seats and having t eir upper surfaces eonformin to the under surfaces of the rail and llet against which they are adapted toadjust themselves as the wear uponthe chair-seeand insulated means for holdingythe ehair to the rail, `as set forth.
